Definitions
- the invention relates to a deflectable mounting of a boring bar carrying a turning tool on the work spindle of a fine boring machine for producing non-circular bores.
- the free end of the boring bar should also be mounted in the axis of the work spindle.
- Such storage is generally known as tailstock mounting of the boring bar.
- a basic solution to the above task complex is achieved by designing the storage device according to the characterizing features of claim 1.
- the solution to the second part of the task according to the invention namely the mounting of the free end of the boring bar, is based on the kinematic properties of a trapezoidal articulated frame, according to which it is possible to pivot the boring bar attached to it so that it is free End in the axis of rotation of the work spindle at a fixed point can remain stored.
- This property is guaranteed at least for small swiveling angles of the boring bar, which, according to the invention, is solely important.
- a small swivel angle is understood to mean those angles which are generated by a displacement of the relevant hinge points of the hinge frame by less than approximately 1 mm.
- FIG. 1 shows the principle of an articulated frame according to the invention which can be pivoted by a piezo motor as a boring bar bearing device
- FIG. 2 shows a perspective view of an articulated frame on a work spindle with a boring bar attached
- Fig. 3 is a view of a special design of an articulated frame
- a boring bar 1 is articulated on the work spindle 3 of a fine boring machine via an articulated frame 2.
- the boring bar 1 is supported at its free end in a tailstock 4 within the axis of rotation of the work spindle 3.
- the articulated frame 2 can be pivoted relative to the work spindle 3 by means of a piezo motor 5.
- the articulated frame 2 essentially consists of four frame parts which are pivotally connected to one another by four joints 6 in one plane.
- the joints 6 are located on the corner points of a trapezoid.
- the individual joint frame parts form the trapezoidal sides of the trapezoid determined by the joints 6.
- the trapezoid base side 7 is firmly connected to the work spindle 3.
- the boring bar 1 is firmly connected to the short side 8, which is parallel to the long trapezoidal base side.
- the piezo motor 5 is supported at one end on a support 9 which is firmly connected to the trapezoid base side 7. At its other end, it is linked to one of the two short trapezoidal sides 10.
- the piezo motor 5 causes the articulated frame 2 to pivot by expansion and contraction between the articulation points.
- the trapezoidal sides 10 lie with the axis of rotation of the work spindle 3, this center point M not changing its radial and axial position relative to the work spindle 3, at least in the case of the slight pivoting of the articulated frame 2 which is of only interest according to the invention.
- a tailstock mounting of the boring bar 1 is possible in this center M.
- a rotary chisel 13 fastened next to the center point M on the boring bar 1 moves on a circular path K2 when the boring bar 1 is pivoted, which leads to the desired change in diameter to be carried out with the turning chisel during the fine machining of a bore leads ,
- the articulated frame 2 is a one-piece part. This part is made from solid material, for example.
- the material itself can be steel.
- the shape of the joint frame is such that the individual side parts 7, 8 and 10 are each individually rigid, while at their mutual transitions in the sense of the joints 6 they are elastically deformable. This elastic deformability is achieved by constrictions 12 in the regions of the joint frame serving as joints 6.
- the return spring 11 provided in the basic illustration according to FIG. 1 can be omitted since the frame itself is elastically resilient in the constricted areas.
- a piezo motor 5 has the particular advantage that on the one hand the infeed movements can take place very quickly and on the other hand the infeed forces required to apply the cutting forces are also possible without problems.
- an electrical actuator it is possible to control the infeed movements of the motor 5 according to an electronically stored program for a specific shape of the bore to be produced.
Abstract
Montage orientable d'une barre (1) portant un outil de coupe (13) d'alésage sur l'arbre moteur (3) d'une perceuse de précision utilisée pour effectuer des alésages non circulaires. Afin d'obtenir des formes extrêmement précises d'alésage, l'extrémité libre de la barre d'alésage (1) doit en outre être montée dans l'axe de l'arbre moteur (3). Il s'agit d'un montage de barre d'alésage (1) généralement connu sous le nom de montage de contre-poupée. A cet effet, un cadre articulé (2) à articulations (6) situées aux coins d'un trapèze qui permettent au cadre articulé (2) de pivoter dans ce plan sert d'agencement de montage. La base (7) du trapèze est fermement assujettie à l'arbre moteur (3) et le côté (8) court opposé parallèle du trapèze est fermement assujetti à la barre d'alésage (1) axialement alignée avec l'axe de l'arbre moteur. Un moteur piézo-électrique (5) assujetti du côté de la base (7) du trapèze par articulation sur un des côtés (10) du trapèze peut faire légèrement pivoter le cadre articulé (2). En outre, l'extrémité libre de la barre d'alésage (1) est montée rotative dans l'axe de l'arbre moteur (3), dans un contre-support fixe (contre-poupée) (4) située dans la zone de l'intersection des prolongements des deux côtés (10) restants du trapèze avec l'axe de l'arbre.
